Description
Vectron International has introduced a series of low-pro-
file, low cost, surface mount, Temperature Compensated
Crystal Oscillators (TCXOs) available in frequencies
from 10 MHz to 50 MHz.
The OSC series low-profile (0.09 inch maximum height),
surface mount TCXOs can be mounted using the stan-
dard convection reflow process. The units feature a
PPM frequency vs. temperature characteristic over a
to operating range and operate from a
3.0V or 5V supply. Current drain <2.0 mA. Aging
<1ppm/year and phase noise is -125 dBc/Hz at 100 Hz
and -150 dbc/Hz at 100 kHz.
The OSC series of TCXOs and TCVCXOs has been
designed for pick-and-place mounting and reflow sol-
dering. Units are available on tape-and-reel at no addi-
tional charge. The reel size is 2000 pcs. and is compati-
ble with EIAJ-1009B standards. The low-cost, miniature
units are ideal for wireless handsets, PCMCIA applica-
tions, and GPS receivers.
